    摘要: A method of forming a cobalt disilicide layer and a method of manufacturing a semiconductor device using the same are provided. The method of forming a cobalt disilicide layer includes forming a cobalt layer on at least a silicon surface of a semiconductor device using metal organic chemical vapor deposition by supplying a cobalt precursor having a formula Co2(CO)6(R1—C≡C—R2), where R1 is H or CH3, and R2 is hydrogen, t-butyl, phenyl, methyl, or ethyl, as a source gas. Then, a capping layer is formed on the cobalt layer. A first thermal treatment is then performed on the semiconductor device in an ultra high vacuum, for example, under a pressure of 10−9-10−3 torr, to react silicon with cobalt. Cobalt unreacted during the first thermal treatment and the capping layer are then removed and a second thermal treatment is performed on the semiconductor device to form the cobalt disilicide (CoSi2) layer.
